<P>PROBLEM TO BE SOLVED: To prevent mixing-up of data to be written to a storage device of a change part on a production site of the change part of an image forming device. <P>SOLUTION: A production line code showing a production line 210 is registered in a data writing device 230 installed in the production line 210. A production line code showing a manufacture line of the change part that is a writing destination of data is incorporated in the produced writing data in a data management department. When installing the writing data, the data writing device 230 compares the production line code included in the writing data with the production line code stored in itself. When they do not match, the data writing device 230 decides the mixing-up of the writing data and displays an error message. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
